HEINRICH HELD, OF LOEGHGAU, VURTEMBERG, GERMANY, ASSIGNOR TO PLACE.

STOPPING MECHANISM FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 414,837, dated November 12, 1889.

Application filed August 6, 1889. Serial No. 319,859. (No model.)

T0 to whom it may concern.-

Be it known that I, HEINRICH HELD, residing at Loechgau, near Besigheim', Wiirtem-' tures of improvement more fullypointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of my improved stopping mechanism, showing it applied to an engine. Fig.2 is aside view of the stopping mechanism alone, showing the reverse side of Fig. 1. Fig. 3 is a plan of Fig. 2; Fig. 4, a section on line a b, Fig. 2; and Fig. 5 shows an arrest attachment of the check-rope.

The letter r represents the slide-rod of an engine, having atorked end that embraces the eccentric-rod 5. close to the joint with the slide-rod a support E, to which is pivoted a bent lever O. The

coupling-bolt G of the shafts r s is of such a length as to project at both ends beyond its seat. It is provided witlia notch g, arranged vertically in relation to the longitudinal axis of the bolt. The notch g is engaged by one end of the lever C. Upon the opposite end of bolt G there is placed a spring H, which has a tendency to throw the bolt out of its seat as soon as the bolt is liberated from engagement with lever O. The lever C carries on its horizontal arm 'a counter-weight c, that holds the lever in engagement with the bolt while the machine is in operation. To the upper end of lever G there is secured the check rope or wire F, that passes through the several rooms of the shop. The eccentric-rod 5 may be suspended trom the ceiling in such a manner that when the slide-rod is uncoupled the rod 5 is raised at its disengaged end.. To this cf- 17 feet a lever L, pivoted to a hanger L, carries on one arm a counter-weight Z, while the other arm supports the shaft 5 by means of a suitable leather strap Z' and wire Z Vhen the the check-rope F The eccentric-rod s carries check-rope F is pulled, the lever C becom s disengaged from bolt G and the latter is thrown out of its seat, either at once or after the engine has arrived at its dead-point position. The eccentric-rod s will thus be raised by counter-weight l, or when this arrangement is not employed it will fall to stop the engine.

My improved stopping mechanism, owing to its great simplicity, may be applied to any f and bell-crank g connects with check-rope F. A spring 2' has a tendency to hold cablef taut.

When a person is caught byabeltorby the transmission and is thrown against the wire f, will be pulled to stop the engine.

I claim as my invention 1. The combination of slide or valve rod 1' and eccentric-rod s with a notched connecting-bolt G and with a lever engaging said bolt and connected to the check-rope, substantially as specified.

2. The combination of slide or valve rod 0" and eccentric-rod s with notched connectingbolt- G, spring H. lever 0, connected to the check-rope, and with the weight 0 upon said lever, substantially as specified.

3. The combination of slide or valve rod '2" and eccentric-rod s with notched connectingbolt G and with a lever engaging said bolt,

and with check-rope F,connected to said lever,

and with cable f, rope f, bell-cranks g g, and spring 6, substantially as specified.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.

HEINRICH HELD.
